Difference between C and C++. CC++Differences

C programming Language

C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.

In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard.

The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons −

• Easy to learn
• Structured language
• It produces efficient programs
• It can handle low-level activities
• It can be compiled on a variety of computer platforms

C++ programming Language

C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming.

C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.

C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language and originally named C with Classes but later it was renamed C++ in 1983.

C++ is a superset of C, and that virtually any legal C program is a legal C++ program.

Note − A programming language is said to use static typing when type checking is performed during compile-time as opposed to run-time.

Object-Oriented Programming

C++ fully supports object-oriented programming, including the four pillars of object-oriented development −

• Encapsulation
• Data hiding
• Inheritance
• Polymorphism

Differences

Following are the important differences between C and C++.

Sr.No.	Key	C	C++
1	Developer	C developed by Dennis Richie between 1969-1973 at AT&T Bell Labs.	C++ developed by Bjarne Stroustrup in 1979.
2	OOPS	C does not support OOPS concepts like polymorphism, encapsulation, and inheritance.	C++ is a object oriented programming and supports OOPS concepts like polymorphism, encapsulation, and inheritance.
3	Set	C is a subset of C++.	C++ is superset of C. All code of C can run in C++ but vice versa may or may not be true.
4	keywords	C has 32 keywords.	C++ has 52 keywords.
5	Procedural vs OOPS	C is a procedural programming language.	C++ supports both procedural as well as object oriented programming.
6	Data and Function	Data and Functions are separate in C.	GData and Functions are encapsulated together as object in C++.
7	Information Hiding	Information Hiding is not supported in C.	Information Hiding is supported in C++ via encapsulation.
8	Overloading	Function and Operator overloading is not supported in C.	Function and Operator overloading is supported in C++.
9	Function	C is function driven language.	C++ is Object driven language.
10	Structure	C structure do not support defining functions.	C++ Structure supports defining function.
11	Reference Variables	Reference Variables are not supported in C.	Reference Variables are supported in C++.
12	Virtual and friend functions	Virtual and friend functions are not supported in C.	Virtual and friend functions are supported in C++.
13	Exception Handling	Exception handling is not supported in C.	Exception handling is supported in C++.
